SAFETY-RAZOR FRAME.

Specification of Letters Patent.

Patented J an. 2, 1912.

Application filed November as, 1910. Serial No. 594,443.

To all whom it may concern: 1

Be it known that I, RICHARD Knnrrn, a citizen of the United States of America, residiiigat the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Safety-Razor Frames, of which the following is a full, clear, and exact des'cri tion. I g his invention relates to safety-razor frames, more particulif'rly to the blade clamping plates thereof, the object being to rovi'de in jjblade in position in a frame therefor.

ne of'the main objects of my improvement is to provide a double locking mechanism for the'blade.

To carry out the function of firmly doubly locking the blade in posit ion,'I'provide-a "spe'cially formed clamping plate and a cooperating catch onthe razor frame. 1

Other features of improvement will hereinafter appear. I will now proceed to describe my invention in detail, the novel features of which I will 'finally claim, reference bein had to the I a D accompanying drawing, wherein Figurel is a front elevation of'asafety I razor embodying my improvement; Fig. 2 $0 is an enlarged vertical sectional view thereof, thesection being taken on a line a-a in Fig. 1, a portion of the frame and handle being shown in elevation; and Fig. 3 is a Referring to the drawn a safety-razor frame is indicated by 1, the said frame being provided with the usual guard fingers 2 and stops 3 for limiting the downward position i of the cutting blade 4. The blade herein illustrated is of the type having a rounded heel piece 5.

.My improvement consists essentially of the clamping-plate 6 and catch 7 on the frame '1, which is designed to engage the I 4 upwardly extending latch or finger 8 on the plate 6.- The clamping-plate 6 is also provided with a handle 9 for manipulating the saidplate. The clamping-plate 6 is pivot ally connected to the frame 1 as at 10.

1 By referring to Fig. 2 it will be seen that frames,

a clamp that will firmly hold a cut-- ing plate 6,

top plan viewthereof on a reduced scale. 1

ceive the upper end of the on the plate 6.

When the frame 1 and clamping plate 6 are made from the proper material, the said material being comparatively thin metal 5 such as is usually used for safety-razor the latch 8 and catch 7 Willbe slightly yieldable or resilient.

For the purpose of pressing the blade 4, at the lower end thereof, against the frame 1, I. provide the clamping-plate with a longitudinally disposed projecting ridge 13, which is adapted to contact with the blade 4 and press it against the frame 1, when the clamping-plate 6 is looked, as shown in Fig. 2. The ridge 13 is located intermediate the pivotal point 10 and latch 8 as shown.

By meansof the herein described c1ampprovided with the-latch 8, and the catch 7 on the frame 1, I am able to doublysecure the cutting blade 4 in the frame 1 for the reasons, firstly, that as the clamping-plate is provided with the said ridge or projection 13, which contacts wit-h the cutting blade, and that the said clamping-plate is provided with a member which extends over and contacts with the heeliece 5 on the cutting blade, the said cutting lade is prevented from moving upwardly when inuse, also outwardly at the bottom thereof. Secondly, by virtue of the catch 7, which engages the latch 8 at the upper end thereof, the clamping-plate 6 is prevented from prematurely opening and allowing the blade 4 to become loose.

It frequently happens that, owing to an imperfect pivotal connection between the clamping-plates now in use, and the frame of the razor, the cutting blades will chatter, and it is one of the objects of my invention 9 to provide a means that will obviate this objection. Qwing to the resiliency of the catch 7 and latch 8, the lost motion, if any, at the pivotal point 10 will be taken up. Furthermore, the resiliency of the said catch and latch will compensate for slight differences in the width of thecutting blades. The concavity 11 in the latch 8 permits the said latch to grip the blade 4, when the latch 8 is forced over the heel piece 5. The interlocking of the blade and clamping plate is a novel feature, inasmuch as the frame and blade 4 have to be separated, one from the other, by a slight pressure. For

latch or finger 8 this reason the danger of dropping the blade out of the frame, when the catch is pulled upwardly to free the latch 8 is obviated. In

other Words, the clamping-plate 6 will not drop, by gravity, when-the latch 8 is cast free of the catch .7, thereby allowing the cutting' blade to drop out.

It will be seen by referring to Figs. 1- and 2 that the finger, or latch, 8 is integral with the plate 6 and that the said finger extends rearwardly from the plate 6 and over the heel of the cutting blade, the said finger referred to.

being provided with-the concavity 11 above indicated by 15, and thence forwardly as indicated by 16, the handle 9 being an exc pies of tli is Patent may be obtained toi' five ccntsea'ch, by addressing the Commissioner of latents,

tension of the forwardly extended portion 16-. The members 14.- and 15- of the finger 'form that part-of the said finger, or latch, which; engages with the catch 7 on the plate 1.; 1W Having 'noW described my invention, what I claim and desire to secure by Letters Patent is 1. A safet Rearwardly of the point at razor comprising a frame, a cutting bla e earned by sa1d frame, a I

outer surface of the heel 'of the blade, andlocking means carried by said frame in engagement withsaid overlapping finger..

2, A safety razor comprising a frame, a cutting blade carried by said frame, a clampin plate pivotally mounted on 'said frame an contacting with said blade intermediate the top and bottom thereof, a resilient fingercarried by said clamping plate overlapping the heel of said blade, saidfin ger being provided with a concavity, said concavity receiving a portion of the outer surface of the heel of the said blade, and a resilient catch carried by said frame, in ens ga ement with said finger; U W
